I don't know how you managed to get this error but there went something terribly wrong. The thing is that you managed to break a Minecraft method which can't fail under normal circumstances. Do you have any special world plugin or a anything that changes the world files installed? A list of your plugins could help. How fast is the HDD of your server?

I actually had to uninstall the plugin. It had been running fine for a few weeks, then suddenly this error starting coming up , until eventually the server would crash. I can send the crash report as well if you like. As far as i am aware the hdd is an ssd, but i may have to check that, since i've recently migrated the server. Here's a list of my plugins: WorldBorder, MultiWorld, TuxTwoLib, bPermissions, MultiInv, EnchantAnything, Minequery, WorldEdit, Skript, BOSEconomy, LogBlockQuestioner, Vault, LogBlock, LWC, stables, WorldGuard, HeadHunter, WGRegionEvents, Shopkeepers, SurvivalGames, CompatNoCheatPlus, XPSet, EpicBossRecoded, ClassicPortals, WGPFix, ClearLag, ScheduledAnnouncer2, ProtocolLib, Votifier, WGCustomFlags, FoundDiamonds, AntiChat, XBP, Essentials, AntiCommandTab, EssentialsProtect, NoCheatPlus, ServerSigns, EssentialsSpawn, DeathControl, Enjin Minecraft Plugin, HealthBar, EssentialsAntiBuild, VotifierScripts, WGRegionCommands, EssentialsChat, Factions, ecoCreature.

The only one i can think that may be causing the problem is ClearLag (recent addition for item drop removal), it may be something to do with mob removal, even though i have mob removal turned off. I was running the previous 1.6.4 RB of craftbukkit, now i am running the latest one. With either build, i was still getting the error and eventual crash.

I'm sorry that you had to remove the plugin :/

I don't think any of your plugins is causing this problem.

The crash-report could be helpfull, give me anything that can help me to find the problem :smile:

I'm devastated i've had to remove it, it's our favourite plugin on the server. (fantastic job on it btw). Here's the crash report: http://pastebin.com/VP6FdWkw

Thanks for your time :)
